Regular maintenance ensures your Mitsubishi continues to run beautifully and looks its best. It can even extend its lifespan by spotting small problems before they have a chance to cause damage. Following the recommended Mitsubishi maintenance schedule for your model keeps costs down and helps prevent inconvenient breakdowns.
Mitsubishi Maintenance Schedule: Keeping Your Vehicle Reliable
The precise requirements for your Mitsubishi may vary depending on your model, your driving habits, and the weather where you live. It’s therefore a good idea to check your owner’s manual or speak to your local Mitsubishi dealership to get an exact schedule. However, most Mitsubishi maintenance will follow a schedule that looks roughly like this:
3,750 Miles or Three Months
At 3,750 miles or three months, whichever is sooner, your Mitsubishi should have its first service. This only requires a few basic maintenance tasks:
- Check and/or change fluids including engine oil, brake fluid, coolant, and power steering fluid
- Rotate tires
- Replace engine oil filter
- Check cabin air filter
7,500 Miles or Six Months
When you reach either 7,500 miles or it’s been six months, a slightly more in-depth service is due. This repeats everything included in the three-month service, but also adds the following checks:
- Brake pads and rotors
- Suspension
In addition, at this point the cabin air filter should be replaced, rather than just checked again.
15,000 Miles or 12 Months
The most comprehensive maintenance checks are required once you’ve driven 15,000 miles or reach 12 months. This includes everything from the six-month check but also adds:
- Replace engine air filter
- Change spark plugs
- Check automatic transmission
- Check wheel cylinders and rear drum brake linings
- Check brake hoses
- Check driveshaft boots
- Inspect tire repair kit
- Test the battery
Mileage-Specific Maintenance
As well as the maintenance that should be done at certain time intervals, some additional maintenance needs to be carried out once you’ve driven a specific number of miles:
30,000 Miles
- Change of transmission fluid
- Full coolant flush
50,000 Miles
- Check steering system
- Change fuel filter
- Inspect exhaust system
100,000 Miles
- Replace timing belt
- Replace water pump
- Check full brake system
150,000 Miles
- Check the full cooling system
- Transmission service
- Check full electrical system
Maintenance Tasks to Carry Out at Home
It’s essential to get maintenance carried out by Mitsubishi at the recommended intervals, but you should also do some simple routine maintenance at home, namely:
- Washing the exterior
- Checking your lights
- Maintaining the right tire pressure
- Checking the tire tread
- Topping off windshield wiper fluid
